Function Documentation

char* strcrop (  char *  s  )

Remove blanks at the end of a string. Parameters: s  String to parse. Returns: ptr to statically allocated string. This function returns a pointer to a statically allocated string, which is identical to the input string, except that all blank characters at the end of the string have been removed. Do not free or modify the returned string! Since the returned string is statically allocated, it will be modified at each function call (not re-entrant).

char* strlwc (  char *  s  )

Convert a string to lowercase. Parameters: s  String to convert. Returns: ptr to statically allocated string. This function returns a pointer to a statically allocated string containing a lowercased version of the input string. Do not free or modify the returned string! Since the returned string is statically allocated, it will be modified at each function call (not re-entrant).

char* strskp (  char *  s  )

Skip blanks until the first non-blank character. Parameters: s  String to parse. Returns: Pointer to char inside given string. This function returns a pointer to the first non-blank character in the given string.

char* strstrip (  char *  s  )

Remove blanks at the beginning and the end of a string. Parameters: s  String to parse. Returns: ptr to statically allocated string. This function returns a pointer to a statically allocated string, which is identical to the input string, except that all blank characters at the end and the beg. of the string have been removed. Do not free or modify the returned string! Since the returned string is statically allocated, it will be modified at each function call (not re-entrant).

char* strupc (  char *  s  )

Convert a string to uppercase. Parameters: s  String to convert. Returns: ptr to statically allocated string. This function returns a pointer to a statically allocated string containing an uppercased version of the input string. Do not free or modify the returned string! Since the returned string is statically allocated, it will be modified at each function call (not re-entrant).
